JOHN L. BARTLETT,OF STOOKTON, ASSIGNOR FOR ONE-HALF HIS RIGHT TO WILLIAM BIV EN, OF SAN JOAQUIN COUNTY, CALIFORNIA.

IMPROVEMENT IN GAS-CARBURETERS.

Specification formingpart of Letters Patent No. 107,853, dated October 4, 1870.

To all whom t may concern:

Be it known that I, JOHN L. BARTLETT, of Stockton, in the county of San Joaquin and State of California, have invented a new and useful Improvement in Gas-Machine 5 and I do hereby declare that the following is a full, clear, and exact description thereof, which will enable others skilled in the art to make and use the same, reference being had to the accompanying drawing forming part of this specification.

This invention. relates to a new and useful improvement in machines for generating illu-V minating gas by carbureting atmospheric air;

`and it consists iu the construction, arrangement, and combination of ,parts hereinafter described.

In the accompanying drawing, Figure l represents a vertical central section of the machine. Fig. 2 is a horizontal section of Fig. l on the line w Fig. 3 is a horizontal section of Fig. l on the-line y y.

Similar letters of reference indicate correspondin g parts.

This machine consists mainly of two or more separate carbureting-chambersfa gas or carbureted air-holder, ablower for supplying air,

and areservoir for the hydrocarbon liquid, with the pipes connected therewith.

A is the lower carburetingchamber. B is the upper one. O is the gasometer or holder. D is the blower, by means of which air is forced into the lower chamber A through the pipe E. F is the fountain or reservoir, which contains the gasoline, naphtha, or other hydrocarbon liquid for carbureting the air. G is a case or receptacle for the blower, which is placed on the gasometer, which, with the carbureting chambers A and B, are secured together by means of the rods H. The fountain F is supported by two of these rods H. The carburetin g liquid is `discharged into the upper chamber B through the pipe I, and from that chamber into the chamber A through the pipe J. The ow of the liquid into these chambers is regulated by means of oats K, which are made to operate stop-valves. The upper iioat also indicates the height of the liquid in the upper chamber by means of a pointer thereon,which atmosphere at one end for the admission of' the air. VAt the other end they open into the interior cylinder, from which the air passes into the pipe E through the journal of the blower, which is hollow. The air is conveyed down under the machine, and up through the bottom of the chamber A, into the air-receiving chamber N, through a valve, to prevent a return of the air, from whence it is discharged into the perforated arms O, beneath the surface of the liquid. The air takes 'up or combines with a portion of liquid, and becomes partially carbureted in the chamber A, but passes directly upward through the tube Pinto the receiving-chamber q, from whence it is again forced into the liquid from the perforated arms R, and rises from the liquid and chamber B into the gasometer O throughthe tube S, from whence it is discharged ready for use through the pipe T. The gasomcter O is confined in the watertank U.

V is a tube provided with a stopfcock for drawing off the water from the tank. WV is a tube for drawing oft' the carbureting liquid from the chamber A.

The blower D may be rotated by means of a spring or weight and clock-Work or gear ing, or in any other suitable or convenient manner.

By this machine atmospheric air may be charged with the vapor of thevhydrocarbon liquid at avery slight expense, so as to give a most brilliant light.

This entireV apparatus is in a very portable shape, and well adapted to family use, as well as for supplying any greater number of burners, the number of burners being regulated by the number o f carbureting-chambers.

Having thus described my invention, I claim as new and desire to secure by Letters Patentl. The fan-blower D, consisting of two cyl= iuders connected by spiral channels m, open dial perforated arms O arranged in the hyto the air at one end, and discharging the air drocarbon-chamber A, as and for the purpose into the interior cylinder at the other, condescribed. structed as and for the purpose described. JOHN L. BARTLETT.
